Glacier Hills Ultra 50k

The Glacier Hills Ultra 50K is a trail running event held annually at Newton Hills State Park near Canton, South Dakota. Scheduled for November 1, 2025, it offers three race distances: 20K, 30K, and 50K, each consisting of multiple loops on a challenging 10K course with approximately 850 feet of elevation gain per loop. The course features a mix of horse and hiking trails, steep climbs, descents, and scenic wooded terrain.

Runners start early to avoid horse trail conflicts and must finish within strict time cutoffs. The event emphasizes a fun, grassroots atmosphere with aid stations, drop bag options, and unique swag. Participants can also earn a special "Betty the Yeti" award by completing all distances over time. Visit the organization's website for the most recent information.
